LONG BEACH — Razor clams on Long Beach Peninsula continue clearing out the domoic marine toxin they absorbed last summer from algae they eat.
The seven-day clam dig set to start this Thursday, Jan. 21, was approved after Washington Department of Health tests found domoic levels of 18 parts per million at the reserve near Surfside, 5 ppm in the middle sands of the Peninsula and 12 ppm on the south end. Tests were conducted either Jan. 13 or Jan. 14. All are an improvement on the previous round of testing.
The other open Washington beach, Copalis around Ocean Shores, had test results of 9, 11 and 8 ppm.
Two beach areas remain closed:
• Mocrocks Beach (just north of Copalis); which includes Iron Springs, Roosevelt Beach, Seabrook, Pacific Beach and Moclips)
• Twin Harbors Beach; which includes Westport, Grayland and North Cove
The Twin Harbors area is important to residents of north Pacific County, for whom it is a quick car trip on State Route 105. The most recent test results there were 20 ppm in the north, 31 ppm in the middle and 23 ppm in the area nearest the mouth of Willapa Bay.
Results at Mocrocks were 21 ppm in the north, 18 ppm in the middle and 8 ppm in the south.
For a dig to be allowed, all results on a beach must be 19 ppm or less.
